@D2xhale said in DIY heated bed not heating fast enough, keeps faulting:

I have tried auto tune and get a similar fault error relating to the time it is taking to get to temperature.

You mean you get an error during tuning, or after using the tuned results?
What results did it tell you to use after tuning?
Did you save those results with M500 or manually enter it in config.g?
Do you have a config-override.g file?
Where is your thermistor located?
Can you share a photo of your bed setup?
What does your heater graph look like?

The Duet has no knowledge of the microstep setting of your external driver, and RepRapFirmware ignores M350 settings for external drivers. The microstepping will be whatever you have set the external drivers to using the switches on it.

Do not connect any of the output pins of the expansion board to ground. They are all differential outputs, so doing so may burn out the driver chips on the expansion board. Instead, connect GND on the G540 to GND on the Duet, or to GND on one of the servo output connectors on the expansion board.

No, the voltage between each pair of outputs pins should always be either about +4V or about -4V.
